Description

When you call code completion by pressing Ctrl+Space and then use up/down arrow keys to select an item selection sometimes the selection bar skips every second item. At the same time the context sensitive help becomes useless, because when you press Ctrl+F1 it will show you the code completion help. If you want to continue working normally on your project you have to close all open files in the editor (loosing all your bookmarks) and reopen every file you worked on.

This is in my opinion a very annoying bug. I tested it with Delphi 7 Professional (English) on Windows XP Pro and Delphi 7 Personal on Win2K.

Steps to Reproduce:

It took me some time to find a safe way to reproduce this bug, but here is at least two ways to do it: (There seem to be more ways I haven't been able to identify yet)

1.
Start Delphi and Double-Click on the blank Form to create (for example)
TForm1.FormCreate(Sender: TObject);
begin
|
end;

(*)
Your cursor is at the "|". Now press Ctrl+Space to invoke code completion.

Then hold Ctrl down and click on "Self : TForm1" (or any other item)

Press Ctrl+Space again to invoke code completion. Now press down arrow key. You will notice that the blue selection bar jumps from "Self" to Formcreate skipping "Sender", press down again and it will jump to "Cascade" skipping "ArrangeIcons".

If this isn't enough skipping you can repeat repeat from (*) to here and it will skip two items, or even more.
----------------------------------------------------------------------------
2.
Start Delphi and open a second Unit (for example Forms.pas).
Double-Click on the blank Form to create (for example)
TForm1.FormCreate(Sender: TObject);
begin
|
end;

(*)
Your cursor is at the "|". Now press Ctrl+Space to invoke code completion.

Then press Ctrl+Tab to switch to Forms.pas in the editor (or press F9 to compile the program)

Press Ctrl+Space again to invoke code completion. Now press down arrow key. You will notice that the blue selection bar jumps from "Self" to Formcreate skipping "Sender", press down again and it will jump to "Cascade" skipping "ArrangeIcons".

If this isn't enough skipping you can repeat repeat from (*) to here and it will skip two items, or even more.
---------------------------------------------------------------------------
After you did 1. or 2. put cursor on code (for example FormCreate) and press Ctrl+F1. This will open Code completion help instead of context sensitive help for the keyword your cursor is at.

I've seen this a lot of times as well. I also agree that this can be very annoying! Good report.

Additionally I would mark 2368 as a duplicate of this one and not vice versa as this report is much more comprehensive.

2368 is not about code completion.

Oops. Sorry. Unfortunately I can't find the report which I originally had in mind.

I frequently encounter this problem as well, but haven't been able to reliably reproduce it. Good job Sebastian.

You can also reproduce this if you press F9 (to compile the program) while the code completion window is open.

Rodrigo Laurindo at 5/6/2003 5:53:30 AM -

We can easily reproduce it now. What about open it?

This bug is NOT fixed in Delphi 7 Update 1, even though the readme claims that it is. I am currently looking at a code completion dropdown which still skips items when you press the up or down arrows.

Do the steps in this report still show the problem? If so, which patch did you apply, e.g. Pro or Enterprise and what language?

Pierre le Riche at 5/13/2004 12:13:37 AM -

It appears that these steps no longer produce the bug, so at least it is partially fixed. I will try to obtain steps to reproduce the remaining cases in which the bug exposes itself and post a new QC report.

Craig Farrell at 5/12/2004 12:14:57 PM -

This report has two sets of steps, both of which show the problem before the patch and do not show the problem after the patch. I suggest adding a new QC report with your steps and preferably your project attached that shows the problem you still see.
